Tips and tricks

You cannot start more than 2 workers, but you can add as many user IDs as you wish. This allows you to generate/view reports for any number of users if there is any data on their USER_ID. So, you can either periodically start/stop stalkers OR if you're lucky and someone else has collected (or is collecting) some data on USER_ID, you can generate reports without ever starting the stalker.

There is a console interface that provides the same functionality as the web interface (stalk/report). Just follow the setup steps.

You can run just the stalker, to collect data. By default it will output plenty of log messages and data, to prevent this, change the log_level in config.json

Take a look at config.json. You can add custom fields to be parsed, by specifying the type, selector and name (this will work for renaming currently scraped fields, however, reports and other output might break because of missing data)
